I'm curious:

- do you use these in 'ultrawide' mode (3840x1080)?

- if so, do you find the head tracking works well (i.e. it just works)?

- do you notice the lack of vertical resolution?

(I don't own a pair of these or similar, and like the idea. But a portable monitor gives me a second screen in addition to my MBP. AIUI the glasses would mean I would no longer be able to see my MBP screen, so the glasses would be a substitute, not a complement.)
